Using async to sleep in a thread without freezing [closed]
So I a label here (""). When the button (button1) is clicked, the label text turns into "Test". After 2 seconds, the text is set back into "". I made this work with a timer (which has an interval of 2000):
private void button1_Click(object sender, EventArgs e)
{
label1.Text = "Test";
timer.Enabled = true;
}
private void timer_Tick(object sender, EventArgs e)
{
label1.Text = "";
}
This works; however though, I am curious about making it work in an async method.
My code looks like this currently:
private void button1_Click(object sender, EventArgs e)
{
label1.Text = "Test";
MyAsyncMethod();
}
public async Task MyAsyncMethod()
{
await Task.Delay(2000);
label1.Text = "";
}
This doesn't work though.
Solution 1:
As I mentioned your code worked fine for me, But perhaps try setting your handler to async
and running the Task.Delay
in there.
private async void Button_Click_1(object sender, RoutedEventArgs e)
{
label1.Text = "Test";
await Task.Delay(2000);
label1.Text = "";
}
